7 , with fully electrically isolated soft start control interface (short circuit start / stop stop), easy to connect with the thermostat; with 12V / 24V input start / stop mode control interface, easy to connect with various solid state relays (with voltage input work On the contrary, stop heating, also note: when using this function, the soft start interface should be empty, and the shorting ring needs to be removed), the control response speed is fast, the starting time is < 1S ;

8 , with heating coil short circuit, open circuit protection function, 130% overload and no-load transient protection function, instantaneous protection response time ≤ 2uS ;

9. Wide coil compatibility, compatible with the same model of other companies;

10 , strong anti-interference ability, can control 30 controllers simultaneously start / stop at the same heating body without mutual interference;

11. Open application platform, users can automatically read the important parameters such as current, frequency, phase difference, temperature, etc. with our dedicated digital programming display. It can also set various application parameters according to the needs, making installation and debugging more simple and convenient;

12 , can set 1 ~ 255 days working time, the time is automatically closed, you need to enter the password to restart ( if necessary, the factory password, please consult the manufacturer ) ;

13 、Using industrial grade components, 100% high temperature aging test, ensuring continuous and reliable operation in the industrial environment of 50 °C for 24 hours, the average fault-free service life: ≥ 50000Hrs ;

14 、Product standard factory: control board, heat sink and cooling fan integrated, equipped with chassis and digital programming display;

15 , the physical size of the controller: length 220mm * width 130mm * height 140mm (including chassis);   

Fourth, the company's electromagnetic heating controller advantages

1. The power supply adopts wide voltage design and constant power output from 210V to 260V , which is especially suitable for occasions where the grid voltage fluctuation is large;

2 , using double 60A imported IGBT half-bridge series resonant structure, product quality is more stable, anti-interference ability is stronger, long-term continuous work does not burn the board;

3 , increase 0 ~ 5V or 4 ~ 20mA analog PID control interface, control power output, make heating temperature control more accurate, more suitable for the production of various heating equipment;

4 , increase the 12V/24V voltage control interface to facilitate the use of solid state relay control;

5 , the introduction of Japan's advanced production technology, the product has undergone rigorous functional testing and aging test before leaving the factory, the quality is effectively guaranteed;

6 , the national unified warranty for 1 year, product life-long maintenance, the entire process of technical guidance and service, so that you have no worries!  

Five, system wiring instructions and schematics

1 , three indicators, Power : power indicator ( red ) , Work : work light ( green ) , Failure : fault light ( yellow ) . Work and Power during normal operation in a bright, Failure off; when made in circuit failure Failure flashes when   When the Work light is shining, it indicates that the coil load is being detected.  

2 , Soft Boot ( green socket )   This interface is a soft start / stop control interface that works when shorted and stops when disconnected.

3 , AC-L and AC-N are 220V power input, OUT1 and OUT2 are output terminals connected to the heating coil.

4 , coil reference parameters:

Mica wrapped glass fiber woven high temperature resistant cable, cross section national standard 4mm 2 inductance is 100 ~ 150uH , about 20 ~ 25m , the thickness of the insulation cotton is required to be about: tubular coil 15 ~ 25mm , flat coil: 10 ~ 15mm , the working current of the quota: 10 ~ 12A , the general working frequency is: 10K ~ 20KHZ .
